Each year, disasters around the world kill nearly 100,000 and affect or displace 200 million people. Many of the places where these disasters occur are literally 'missing' from any map and first responders lack the information to make valuable decisions regarding relief efforts. Missing Maps is an open, collaborative project in which you can help to map areas where humanitarian organisations are trying to meet the needs of vulnerable people.

It is no problem if you have never mapped before - it doesn't take long to learn. Visit our beginners section to find out how. If you already know how to edit OpenStreetMap, feel free to just get started.

Organizing mapathons is a fantastic way to build a community of mappers all focusing on the same area of the world. It is also a great learning environment, where new mappers can learn from the experiences of others. Mapathons are organised by groups and individuals all over the world.

A donation to the Humanitarian OpenStreetMap Team (one of the founders of Missing Maps) can help to support local people in mapping their own communities, to develop tools and processes so that more people can contribute, and to scale the project so that we can help even more humanitarian organisations responding to crises all over the world.
